I thought you already had a 24V generator on your auxiliary engine. Isn't that good for charging your batteries, or did I miss something?

If you want super efficiency I would have thought maybe a small air-cooled diesel would be the ticket. That Honda looks cool and all, but better suited to situations where portability, power-to-weight and multi-orientation operation are important. For a stationary battery charger, a small diesel would be more efficient,last longer and be more forgiving about what you swill into its tank.

Hi Tim,Just a bit of arithmetic: 720W/28Volts=25Amps. So not much bang for the buck and that's assuming 100% alternator efficiency, so actually a bit less. And also, that's with the little bugger screaming at 7000 rpm. I think i'm with mr. anonymous above.But it is a cute little engine. Maybe it could be adapted for rust busting.Cheers, David

Hi Tim Happy Chtistmas to you! I`m curently using a 1/4 horse mains motor to drive a modified alternator (fot whatever reason) and I get about 35/45 volts "ac" and the motor slows to a stop. so maybe you will have to accept a slow charge using your system? I would be very interested to know just what revs tou can get that honda up to under load and at what amperage the motor stalls.Take care and have a great and productive new year, Regards Rob
